How Is Epilepsy Diagnosed?

Electroencephalography (EEG)

The EEG machine [2] is used to record the electrical activity of the brain. It shows the graphical representation of electrical waves that pass through neurons [3] in the brain. It is a non-invasive procedure [4] and involves attaching electrodes to the scalp.

The electric waves in the brain have a regular pattern, which your doctor or specialist understands. The graphical representation of the electrical waves in someone who has epilepsy is different from that of a normal person. And this can be seen even when you are not having a seizure.

This makes the EEG an important tool used in diagnosing epilepsy.

Positron Emission Tomography (PET) Scans

The use of PET scans allow the injection of a radioactive material into the vein. When this radioactive material passes through the brain, it displays changes in the metabolism happening in the brain. These changes are viewed on a scanning machine and are important in diagnosing various neurological conditions like epilepsy.
